orrgnunnme APPARATUS.

Application Thisinvention relates togano l' burner and consists incertain improvements; upon the oil .burner shown in my Patent No.1,667,042,

. dated April 24, 1928.

In connection with .the aforementioned burner; itwas found that theconical conveyor became extremely hot above the fuel well and too hotfor ordinary purposes.

The primary object of this invention is to overcome this objection ineliminating the conical conveyor above the fuel well and using aplurality of individual pipes which can be more effectively cooled bythe surrounding air.

The invention comprises the novel structure and combination of partshereinafter described and more particularlypointed out and defined inthe appended claims.

In the accompanying drawing, which illustrates a preferred embodimentofthis invention and in which similar reference numerals refer tosimilar features in. the. different views: v

Figure l is a side elevational view of an oil burner embodying thisinvention.

Figure 2 is an enlarged sectional view taken substantiallyupon the lineII-II. of Figure 1. a v

Figure 3is an enlarged sectional view taken substantially upon the lineIII-III of Figure 2 looking in the diretcion of the arrows. Figure 4 isan enlarged sectional view taken upon the line 1v-,-1v of Figure 2looking in the direction of the arrows.

As shown on the drawinglsz r In the drawing there is s own the completeburner comprising a fuel supply pipe 1,

which supplies the liquid fuel to a strainer 2 from which it is pumpedthrough a pipe 3 and a ump 4 into the liquid fuel well 5. A

suitab e pipe 6 connects the pump with the lower end of the fuel well.-The pump is driven by a suitable motor 7 The fuel well 5 consists of a.cylindrical casing which is supported upon v a leg 8. 1 Within thecylindrical well there is suspended a cylmdrical-bearing 9' having anupper annu ar flange 10 which rests upon the upper edge of the well 5. Aconical conve or 11 is rotatably mounted within the g c dricalbearing9'and the u per art of t 's' conveyor *extends a suite le stance abovethe-well for the attachment of apulley whi "ed January 24; 1927. SerialNo. 162,948.

12 whereby the same may be rotated by means of a belt 13 driven from themotor. The to of the conical conveyor is substantially close d by aplate 14 through which a plurality of oil conveying pipes 15 arethreaded. It will be noted that the lower ends of these pipes arelocated adjacent the wall of the conical conveyor which is preferablycut away as indicated at'16 to facilitate the passage of the 011 fromthe conical conveyor to the mouth of said pipes.

The pipes 15 which are three in number extend-upwardly and slopeoutwardly. At their upper ends they are provided with suitable spouts 16for directing the fuelinradial directions. A top plate 17 provided withsuitable apertures 18 forreceiving the pipes 15 1s removably supportedupon the tops of the plpes. The spout couplings preferably form thesupports for sustaining the plate 17. 1

Upon the bottom of the late 17 are a plurality of radially extendingdeflector plates or blades 19 extending from the lower surface of theplate 17 and together therewith serve as a fan which is constrained torotate with the conical conveyor and feed pipes. 15. Above the fan thereis a heat absorbing plate. 20 which is sustained upon a stationary rod21' which extends 'throu h the top plate 14 of the well .and is suitaly. anchored in the bottom of the well by means o'fa threaded socket.Just below the fan there is a cylindrical drip pan 22 provided with anupwardly extending neck 23 surrounding the ipes 15. This 'drip pan orbasin is connected y a pipe 25 with the top of the oil well 5,

The drip pan is supported upon suitable standards 24 supported upon thefloor.

It will be ap reciated that during the operation of the urner, theconical conveyor will rotate and cause the diverging pipes 15 torotatetherewith. As the pipes 15 rotate they will cause a thorough circulationof the air besides being-more directly a,

osed thereto and the tendency for'them to I ecome overheated 'is largelyavoided. In other words, the rotating pipes 15- serve, to

'the air-ad'acentt prec ude the oil om being overheated.

e noziles so as to- I am aware that many changes may be- 1' made andnumerous details of construction may be varied through a wide ranwithout .departingfrom the principles of it inven- 2' v reesgeo tion andI, therefore, do not purpose limiting the patent granted hereon,otherwise than necessitated by the prior art.

I claim as my invention: i

1. In a liquid fuel burner, the combination with a combustion chamber,of a centrifugal member including a relatively long diverging pipesconnecting said centrifugal member to said nozzles, said pipes beingrotatable with said member to elevate fuel to said nozzles and to whipthe air adjacent said nozzles to prevent overheating of the fueldelivered thereto.

2. In a liquid fuel burner, the combination with a combustion chamber,of a centrifugal fuel conveyor operable at relatively low speedsincluding a tube having a conical bore, the largest and of said borecomprising a discharge orifice, a plurality of radial nozzles disposedabove thedischarge end of said tube, an air deflecting plate associatedwith said nozzles, a guide rod extending through said bore and connectedat one end to said plate,means for rotating said tube about said rod,means for delivering liquid fuel to said conical boreincluding acup-like chamber serving as a mounting for the other ends of said tubeand rod, and a plurality of diverging pipes connecting said conveyor tosaid nozzles, said pipes being rotatable with said conveyor to elevatethe fuel from said conical bore to said nozzles and to whip the airadjacent said nozzles to prevent overheating of the fuel.

3. In a liquid fuel burner, the combination with a combustion chamber,of a centrifugal fuel conveyor comprising a tube having a conical bore,the largest end of said bore comprising a discharge orifice, aplurali,ty of radial nozzles disposed above the discharge end of saidtube, an air deflecting plate connected to said nozzles above said tube,a rod extending throu h said bore and i said deflector plate, meansfbrrotating said tube about said rod, means for delivering liquid fuelto said conical bore including a cup-like chamber serving as amountingfor the other end of said tube,.said rod extending clear through saidconical bore and having its other end connected to the wall of saidcuplike chamber, and a-plurality of fuel conveying pipes connected tosaid conveyor, said pipes diverging outwardly and being substantiallyparallel to the conical wall of saidconveyor defining said bore, wherebyfuel is elevated from said bore to said nozzles and the air adjacentsaid nozzlesis Whipped so as to augment the circulation of air undersaid deflector plate. I

4. In a liquid fuel burner, the combination with a combustion chamber ofa centrifugal fuel conveyor comprising a liquid fuel conduit, upwardlyinclined diverging fuel feeding pipes having their lower encs 7connected to said conduit, nozzle means co nected to the upper ends ofsaidpipes, and means for rotating said-pipes and said conduit toelevatefuel from said conduit to said nozzle means and to whip thesurrounding air by said pipes so as to maintain them cool.

5. In a liquid fuel burner, the combination with a combustion chamber ofa centrifugal fuel conveyor comprising a liquid fuel conduit, upwardlyinclined diverging fuel feeding pipes extending from the top of saidconduit, said pipes having their lower ends connected to said conduitadjacent thewall of the conduit, nozzles extending laterally from theupper ends of said pipes and means for rotating said pipes and saidconduit to elevate fuel from said conduit to said nozzles and to whipthe surrounding air by said pipes so as to maintain them cool.

6. In a liquid fuel burner, the combination with a combustion chamber,of a-centrifugal conveyor comprising a liquid fuel conduit, upwardlyinclined diverging fuel feeding pipes having their lower ends incommunication with said condu'itand means Jfonrotating said pipes toelevate? fuel by centrifugal action from said conduit into said chamberand to whip the surrounding air by said pipes so as to maintain themcool.

In testimony whereof I have hereunto subscribed my'name.
